Claims

exact text as granted — not AI-modified
The invention claimed is: 
     
       1. A copolycarbonate, comprising repeat units of the following Chemical Formula 1 and repeat units of the following Chemical Formula 2:
 Chemical Formula 1 
 
       
         
           
           
               
               
           
         
         wherein in Chemical Formula 1:
 R 1  to R 4  are each independently hydrogen, C 1-10  alkyl, C 1-10  alkoxy, or halogen; and 
 Z is C 1-10  alkylene that is unsubstituted or substituted with phenyl, C 3-15  cycloalkylene that is unsubstituted or substituted with C 1-10  alkyl, O, S, SO, SO 2 , or CO, 
 
         Chemical Formula 2 
       
       
         
           
           
               
               
           
         
         wherein in Chemical Formula 2:
 R 5 , R 6 , R 7 , R 8  and R 9  are each independently hydrogen; halogen; 
 
         allyl; C 1-15  alkyl that is unsubstituted or substituted with one or more selected from the group consisting of halogen, C 1-10  alkoxy and C 6-20  aryl; C 1-10  alkoxy that is unsubstituted or substituted with one or more selected from the group consisting of halogen, C 1-10  alkoxy and C 6-20  aryl; or C 6-20  aryl that is unsubstituted or substituted with one or more selected from the group consisting of halogen, C 1-15  alkyl and C 1-10  alkoxy;
 R 10  is hydrogen, C 1-6  alkyl, halogen, hydroxy, C 1-6  alkoxy, or C 6-20  aryl; 
 each X is independently C 1-10  alkylene, —(OCO)—(C 1-10  alkylene)-, or —(COO)—(C 1-10  alkylene)-; 
 each Y is independently hydrogen, C 1-6  alkyl, halogen, hydroxy, C 1-6  alkoxy, or C 6-20  aryl; 
 L is C 3-10  alkylene; 
 Ar 1 , Ar 2  and Ar 3  are each independently C 6-20  arylene that is unsubstituted or substituted with one or more selected from the group consisting of halogen, C 1-15  alkyl and C 1-10  alkoxy; and 
 n and m are each independently an integer from 1 to 999, and 1 is an integer from 0 to 999. 
 
       
     
     
       2. The copolycarbonate according to  claim 1 , wherein the repeat units of Chemical Formula 2 have the following Chemical Formula 2-1:
 Chemical Formula 2-1 
 
       
         
           
           
               
               
           
         
         wherein in Chemical Formula 2-1: 
         R 5 , R 6 , R 7 , R 8  and R 9  are each independently hydrogen; halogen; allyl; C 1-15  alkyl that is unsubstituted or substituted with one or more selected from the group consisting of halogen, C 1-10  alkoxy and C 6-20  aryl; C 1-10  alkoxy that is unsubstituted or substituted with one or more selected from the group consisting of halogen, C 1-10  alkoxy and C 6-20  aryl; or C 6-20  aryl that is unsubstituted or substituted with one or more selected from the group consisting of halogen, C 1-15  alkyl and C 1-10  alkoxy; 
         R 10  is hydrogen, C 1-6  alkyl, halogen, hydroxy, C 1-6  alkoxy, or C 6-20  aryl; 
         each X is independently C 1-10  alkylene, —(OCO)—(C 1-10  alkylene)-, or —(COO)—(C 1-10  alkylene)-; 
         each Y is independently hydrogen, C 1-6  alkyl, halogen, hydroxy, C 1-6  alkoxy, or C 6-20  aryl; 
         L is C 3-10  alkylene; 
         n and m are each independently an integer from 1 to 999; and 
         l is an integer from 0 to 999. 
       
     
     
       3. The copolycarbonate according to  claim 1 , wherein the repeat units of Chemical Formula 2 have the following Chemical Formula 2-2:
 Chemical Formula 2-2
